Symptoms
ENVIRONMENT
-----------------
Oracle JDBC driver (either JDBC Thin or JDBC OCI)
Oracle XML Parser / RDBMS version 11.2
PROBLEM DESCRIPTION
-----------------------------
When uploading an XML file to an 11g database table containing an XMLTYPE datatype stored as SECUREFILE BINARY XML, then very rarely, one of the characters contained within a comments tag will be replaced with a replacement character, such as the hyphen character '-'.
This is seen when fetching that stored XML back out into an output file.
No error is returned; the problem consists of unexpected and unwanted character replacement in the uploaded data as stored in the database.
The problem reproduces with any 11g or 12c version of the JDBC driver; it happens while using either the JDBC Thin or the JDBC OCI driver.
The problem does not reproduce when connecting to a 12c database.
